Hi flossy
Dreams can be a weird, funny, happy, sad and sometimes disturbing experience, depending on your state of mind/ health at the time.
I've had some truly weird dreams eg: where I'm a child with my sisters and caught by a witch and stirred in a cauldron to prepare for her dinner, the witch turning out to be my private school headmistress in Streatham South London, who looked like that witch in The Wizard of Oz!
Or I'm a Indiana Jones style hero, got the girl, and saving the world.....again.
Some say its the thing you're bothered about or think of on the day, that controls what you dream....
I wouldn't let it worry you at all, and try to relax before you go to bed, and think of something pleasant in your life that may have happened or simply animals in a field, yourself in a spa for a day, a nice trip to the hairdresser's ( as long as Edward Scissorhands isn't in it, you should be fine )
Good luck, flossy and please don't let it worry you. x
